It's a bug.
I never really thought of the case where someone had an IPv6 enabled
host and didn't want to use IPv6. Your host has IPv6 by default.
If you don't have any connectivity you can leave IPv6 on and every-
thing should work well, I don't see any reason to turn it off.
If you have IPv6 connectivity and you don't want the server to be
reachable by IPv6 (don't see why), then it makes more sense, but you
could still have access lists to stop IPv6 access if you need to.
So, as a fix you can either turn IPv6 on, or you can try the following
patch to servers/slapd/daemon.c:

+++ daemon.c Wed Sep 6 13:25:46 2000

I'll fix this in a better way for CVS, but I think it should work
well for you.
